I feel sad for you.I don't think you'll get banned just cuz someone has the same device as you, you might have logged in your account in the hackers device. That makes you get the penalty as well. Anyway their decision to suspend the device itself is Right instead of suspending one account only. The hacker could of use the same device but with different account to hack again and never be caught cuz he or she has infinite account to use and hack on the same device over and over again. So yea I really do feel sry for you. Maybe you should make sure tht no one else uses your phone other then you. Well I wish you the best.

Dont worry! If everyone stoled ur account u can change ur gt account password!

U don't even have an account bruh
